[1] "Management Fees" reflects the gross management fees paid to the Manager by the Fund during the Fund's most recent fiscal year and the estimated gross management fee of the Subsidiary for its first full fiscal year.

[2] "Other Expenses of the Subsidiary" are based on estimated amounts for its first full fiscal year.

[3] The Manager has voluntarily agreed to waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund's investment in funds managed by the Manager or its affiliates. The Fund's transfer agent has also voluntarily agreed to limit its fees for Classes B, C, N and Y shares to 0.35% of average annual net assets per class per fiscal year, and to 0.30% of average annual net assets per fiscal year for Class A shares. Each of these expense limitations may not be amended or withdrawn until one year from the date of this prospectus. The Manager has also contractually agreed to waive the management fee it receives from the Fund in an amount equal to the management fee it receives from the Subsidiary. This waiver will continue in effect for so long as the Fund invests in the Subsidiary, and may not be terminated by the Manager unless termination is approved by the Fund's Board of Trustees.
